My Choice? I would use Contreras because we are playing with 3 defenders and would need a wise player in the back. Medel played very good against Honduras, but Ponce made some mistakes that could have been vital. Jara could be good to throw in in the second half if we are chasing a goal.
My Choice? I would choose Carmona because I like his style better. He is young but has experience from his years in Italy. He is a bit shorter and has never scored for La Roja, but his form is very good. Another alternative would be to play Tello in the left. He could brake up a tight Swiss defense better than Carmona or Millar would do.
My Choice? I would start with Fernandez, just because Valdivia can't play for 90 minutes. Fernandez is the ordinary free-kick and corner taker, which has been his specialty in the preparatory games and against Honduras. If he does not play well, as he sometimes does, Bielsa should substitute him as early as possible because he is not the player that gets any better after a rough start. Valdivia always show that he is a good substitute by out-glowing his proceeder at the play-maker role.
